What Are Horizontal Lines?
When looking at the coordinate pairs for an horizontal line, all the y-values will be equal. Yes, the same, no matter what the x-value is. And the line will never cross the x-axis. Check out this tutorial video to see what that actually...

What is a Translation?
A translation means moving a figure to another location by sliding it. The figure, called the image, maintains its size and shape. You can move the image horizontally, vertically, or a combination of both.

How Do You Use a Graph to Translate a Figure Horizontally?
Transformations. Learn a little bit of geometry. See how to translate a geometric figure on a coordinate plane horizontally by sliding it over. Simply pick a point on the figure and count the units you want to move it. Then repeat that...

How Do You Use Coordinates to Translate a Figure Horizontally?
There are many ways to transform a figure on a coordinate plane. This problem requires the movement to be four units horizontally to the right. Using the original coordinate pairs, a positive 4 can be added to each x-value to get the new...

What Does the Constant 'h' do in y = |x-h|?
Translating the graph of an absolute value equation horizontally based on the value of a constant, seems to be a big task. That sentence was a mouthful. So what does it all mean? Click on this video to observe the instructor illustrate...

How Do You Find the Rate of Change Between Two Points on a Graph?
The instructor uses a graph representing time and distance to illustrate how to solve this word problem. She explains each step: rate of change, distance, time, vertical change over horizontal change, change in distance, and change in...
